Radio Frequency Admittance Level Switch

SD RF Admittance Level Switch adopts advanced RF admittance technology to eliminate the interference caused by conductive material buildup. The product mainly consists of a sensor and an electronic unit. The sensor unit comprises three components: measuring electrode, shielding electrode and ground terminal. The material level height corresponds to the admittance variation between the measuring electrode and the vessel wall. When the material reaches the switch operating point, the electronic unit responds and actuates the relay. The shielding electrode prevents false triggering signals resulting from material buildup on the electrode. A switching control signal will only be output once the material truly reaches the set point.
